'Is Bill ok?': Viewers take to Twitter to raise concern over Clinton's shaking hands during his DNC speech as his 'little tremor' condition appears to have worsened

Many viewers took to Twitter to question whether the 69-year-old is having any health issues Tuesday night, after a similar scare occurred earlier this year during an appearance in Iowa in January. 


One concerned viewer wrote during the speech: 'Bill Clinton's hands are shaking a bit. I doubt he's nervous. Am I the only one noticing this? Is he ok?' Clinton has previously spoken about a 'little tremor' he dealt with in his hand and said at the time that it was a condition you 'sometimes get with aging'. However he said he had it checked by a doctor and was assured it was not Parkinson's.
